ARCHIBALD THOMSON DElVAR, OF LIVERPOOL, COUNTY OF LANCASTER,

. ENGLAND.

SHIPS BOAT.

SPECIFICATION forming part of Letters Patent No. 433,854, dated August5, 1890. Application filed November 1, 18-88. $erial No. 289,693. (Nomodel.)

To all whom it may concern.-

Be it known that I, ARCHIBALD THOMSON DEWAR, freight clerk, a subject ofthe Queen of Great Britain, and a resident of 16 Stuart Road, Liverpool,in the county of Lancaster, England, have invented new and usefulImprovements in Ships Boats, of which the following is a specification.

The object of my invention is to provide a ships boat with removableseats, thwarts, and air-cases that are connected to each other in such amanner as to constitute a separate raft-like structure adapted forindependent use in an emergency, or which can be placed as a whole in aboat-shell and be removable therefrom all at once to permit the housingof one boat within another; and to these ends my invention consists inthe construction and combination of parts hereinafter described andclaimed.

Figure 1 illustrates in side elevation an arrangement of the ships boatsand apparatus according to my invention. Fig. 2 illustrates in endelevation the arrangement of ships boats and apparatus shown in Fig. 1.Fig. 3 is a perspective view of the seats and aircases when removed froma boat and according to my invention.

Referring to the drawings, three boats A, B, and C are shown, the boat Bbeing placed inside the boat A, and the boat 0 being placed inside theboat B, the sizes of the boats being such that this can be done. Thethwarts D, seats E, and air-cases F of the boatsA and B are constructedso that they can be removed from the said boats in the form of a raft,as shown in Fig. 3, each raft being fully equipped with oars, masts,sails, and the usual equipment. The means for securing the structureforming the thwarts, seats, and air-cases to the shell of the boatconsist of eyes 6 and bolts e. lVhen not in use, the said structures,with their equipment, can be stowed upon one another on the top of thedeck-house H. The inner boat 0 is a boat of the usual construction"equipped in the usual way.

To lift the boats one out of the other, I use two jibs, one at each endof the boat, and lift the jibs by means of a toothed rack and pinion orlike gear. In the drawings, J J

are the jibs. They are hinged at it to carriages h h. These carriages hh slide on upright standards I I by means of the toothed racks h h andpinions k 7.5. The boat-tackles K K are attached to the heads of thejibs J J, and the lower blocks of the tackles are provided with eyes go,through which the bolts m at the ends of the boat pass. These bolts mmay, to release the boat, be withdrawn in any suitable way-for example,by means of rods 9% 'n, placed along the gunwale of the boat and workedby a lever n, as shown.

To launch a boat, the ends of the tackles K K are secured to the jibs JJ, and by turning the pinions K K by means of their winchhandles K K thejibs J J and the boat attached or hung from them are raised until'theboat is clear of the containing-boat. The jibs are then swung outwardand lowered into the position shown in dotted lines in Fig. 2, and theboat is then lowered into the water in the usual way. The boat can belowered first from the jibs J J into position to embark the passengersfrom the lower deck a, and then lowered into the water, or thepassengers can enter the boat before leaving the containing-boat. Afterthe boat 0 has been raised out of the boat B and while the passengersare embarking in it the raft B, consisting of the thwarts D andair-cases F of the boat B, is removed from the top of the deck-house IIand placed in and secured to the shell of the boat B and then it may belaunched in like manner to the boat 0. Again, when the boat B has beenremoved from the boat A, the raft A, consisting of the thwarts D, seatsE, and air-cases F of the boat A, is placed and secured therein and itis ready for use.

I would have it understood that although I have shown and described aset of jibs or davits suitable for launching boats when stowed inmultiple and according to my invention, any suitable'known kind of jibor davit may be used to launch the boats or to place the raftsconsisting of .the thwarts D, seats E, and air-cases F in the boats. The

said rafts may also be used by themselves as rafts in cases ofemergency.

I am aware that it is not new to house boats one inside another, theunder boat being provided with hinged seats and thwarts so arranged asto be folded and stowed in such a manner as to permit the smaller boatbeing set in place within the larger one; but this I do not claim, and Iam not aware that prior to my invention a boat has been provided withthwarts, seats, and, air-cases connected to constitute a raft separatefrom the boatshell and removable therefrom to permit the housing thereinof another boat-shell or boat, whereby the several boat-shells and raftsare, separate and independent of each other, so that the rafts composedof seats, thwarts, and air-cases can be used alone or be placed in theboat-shells when required.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. The combination,with a ships boat-shell, or aplurality of boat-shells adapted to be housed or stowed one within theother, of a separate raft-like structure or structures constituting thethwarts, seats, and air-cases of said boat shell or shells and capableof being used with such boat shell or shells or separately,substantially as set forth.

2. A ships boat consisting of a shell and a separate raft-like structurecomprising the thwarts, seats, and air-cases, said structure beingprovided with means, as described, by which the structure is secured tothe shell, whereby boats of varying length and beam are capable of beingstowed one within another, and, when required, fitted with saidstructure, or, in cases of emergency, said structure is capable of beingused as a raft and independently of the boat-shell, as set forth.

3. In combination with the shell of a ships boat, the raft-likestructure herein described, comprisingthe thwarts D, seats E, andaircases F, said structure being adapted to be fitted in and secured tothe said shell, orto be used separately as a raft, substantially as setforth.
